'These social bots masquerade as online users, adding posts that seem like they came from real people. But they secretly promote products or viewpoints, and some you might friend use their new connections to siphon off your private information. When coordinated by a botmaster, these social bots can wreak havoc and steal information at a massive scale.
... Furthermore, because so many services build on top of social networks, the risk runs deeper. Many technologies, including data sharing and backups, integrate with sites like Facebook. Their authentication schemes rely on the implicit trust network that social bots are designed to break into.'"
